Abstract
The present invention provides a method of efficiently producing niobium powder, niobium alloy powder, niobium hydride powder or niobium hydride alloy powder for a capacitor, which enables production of capacitor having a high capacitance per unit mass and good leakage current characteristics with narrow variation, and also provides a production method for sinteredbody and a capacitor using the niobium powder, niobium alloy powder, niobium hydride powder or niobium hydride alloy powder. According to the present invention, bygrindingniobiumhydride powder or niobium hydride alloy powder with a grinding aid having a density of 2 to 3.6 g/cm 3 and a fracture toughness value of 1.5 MPa·m 1/2 or more, such as beads made of silicon nitride or a compound containing silicon nitride, a niobium powder with high capacitance can be efficiently produced.
